No
The device description focuses on the physical components and function of a hemodialyzer, with no mention of software, algorithms, or data processing that would suggest the use of AI or ML. The performance studies are described as in vitro and clinical data collected according to FDA guidance for hemodialyzer reuse, not studies related to AI/ML model performance.
Yes
The device is described as being "intended for use in hemodialysis for the treatment of acute and chronic renal failure," which directly relates to treating a medical condition.
No
This device is a hemodialyzer, used for the treatment of renal failure by removing waste products from the blood, which is a therapeutic function rather than a diagnostic one.
No
The device description clearly details physical components like hollow fibers, housing, and ports, indicating it is a hardware device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "hemodialysis for the treatment of acute and chronic renal failure." This is a therapeutic treatment performed directly on the patient's blood, not a diagnostic test performed on a sample outside the body.
- Device Description: The description details a "Capillary Dialyzer" which is a device used to filter blood. This is consistent with a therapeutic device for hemodialysis.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing a sample (blood, urine, tissue, etc.)
- Providing information for diagnosis, monitoring, or screening
- Using reagents or assays
The device is clearly described as a hemodialysis filter, which is a therapeutic medical device.

Device Description
The Gambro POLYFLUX 6 LR, 8 LR, and 10 LR, Capillary Dialyzers labeled for multiple use / reuse are identical in design, materials, function and intended use to the Gambro POLYFLUX 6L, 8L, and 10L Capillary Dialyzers/ Filters labeled for single use which have been previously cleared by the FDA under a 510(k) Notification for single use (510(k) Notification K010985).
These devices are intended for use in hemodialysis for the treatment of acute and chronic renal failure and for certain types of intoxications. They may also be used in cases of acute fluid overload for the removal of plasma water. The membrane used in this device is polyarylethersulfone (PES) which is identical to the membrane utilized in the Gambro POLYFLUX 6L, 8L, and 10L Capillary Dialyzers/ Filters labeled for single use which have been previously cleared for marketing in the United States under 510K Notifications (K010985).
Blood enters a blood inlet port where it is distributed to the hollow fibers. Each hollow fiber has an inner diameter of approximately 215 microns (wet hollow fiber internal diameter) and a wall thickness of 50 microns. The number of hollow fibers in each hemodialyzer / filter is 10,00 for the POLYFLUX 6 LR, 10,000 for the POLYFLUX 8 LR, and 12,500 for the POLYFLUX 10 LR. This effective membrane length is 210 mm for the POLYFLUX 6 LR, and 250 mm for the POLYFLUX 8 LR and 10 LR. The effective membrane surface area is 1.4 square meters for the POLYFLUX 6 LR, 1.7 square meters for the 8 LR and 2.1 square meters for the 10 LR. The housing and end caps of this hemodialyzer / filter are made of polycarbonate.
The fibers used in the Gambro POLYFLUX 6 LR, 8 LR, and 10 LR are of the same composition as those previously approved for the Gambro POLYFLUX L 6L, 8L, and 10L Capillary Dialyzers/ Filters labeled for single use and multiple use (K010985). The patient's blood traverses the inside of the hollow fibers and exits the device via a blood exit port.
By means of a hydrostatic pressure or transmembrane pressure which is created by a combination of positive and negative pressures across the membrane, plasma water along with certain lower molecular weight solutes pass through the membrane and into the dialysate or filtrate compartment of the device. Removal of uremic toxins and waste products are removed from the patient's blood in this device by means of both diffusion and convection through the membrane and into the counter current flowing dialysis solution during hemodialysis. The dialysate exits the devices via a dialysate outlet port.

§ 876.5860 High permeability hemodialysis system.
(a)
Identification. A high permeability hemodialysis system is a device intended for use as an artificial kidney system for the treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration. Using a hemodialyzer with a semipermeable membrane that is more permeable to water than the semipermeable membrane of the conventional hemodialysis system (§ 876.5820), the high permeability hemodialysis system removes toxins or excess fluid from the patient's blood using the principles of convection (via a high ultrafiltration rate) and/or diffusion (via a concentration gradient in dialysate). During treatment, blood is circulated from the patient through the hemodialyzer's blood compartment, while the dialysate solution flows countercurrent through the dialysate compartment. In this process, toxins and/or fluid are transferred across the membrane from the blood to the dialysate compartment. The hemodialysis delivery machine controls and monitors the parameters related to this processing, including the rate at which blood and dialysate are pumped through the system, and the rate at which fluid is removed from the patient. The high permeability hemodialysis system consists of the following devices:(1) The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (K
uf ) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or anther method of ultrafiltration control to prevent fluid imbalance.(2) The hemodialysis delivery machine is similar to the extracorporeal blood system and dialysate delivery system of the hemodialysis system and accessories (§ 876.5820), with the addition of an ultrafiltration controller and mechanisms that monitor and/or control such parameters as fluid balance, dialysate composition, and patient treatment parameters (e.g., blood pressure, hematocrit, urea, etc.).
(3) The high permeability hemodialysis system accessories include, but are not limited to, tubing lines and various treatment related monitors (e.g., dialysate pH, blood pressure, hematocrit, and blood recirculation monitors).
(b)
Classification. Class II. The special controls for this device are FDA's:(1) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Device—Part I: Evaluation and Testing,’ ”
(2) “Guidance for the Content of 510(k)s for Conventional and High Permeability Hemodialyzers,”
(3) “Guidance for Industry and CDRH Reviewers on the Content of Premarket Notifications for Hemodialysis Delivery Systems,”
(4) “Guidance for the Content of Premarket Notifications for Water Purification Components and Systems for Hemodialysis,” and
